Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a cigarette packet conveying device. Background Art

[0002] In the process of cigarette preparation, the packaging and transportation of cigarettes are carried out by automated equipment. After the cigarettes are packaged, that is, after being loaded into cigarette cases, together with the cigarette cases and the cigarettes therein, they are called cigarette packets. The cigarette packets are generally also packaged with transparent paper on the outer layer, so they need to be transferred through multiple workstations on the production line.

[0003] In order to save the occupied space of the overall equipment, a drying conveyor belt for longitudinal transportation is usually used in combination with a synchronous toothed belt for transverse transportation. The suction cups on the extractor located on the side of the synchronous toothed belt away from the drying conveyor belt are used to suck the cigarette packets on the drying conveyor belt onto the synchronous toothed belt, and then the baffles on the synchronous toothed belt are used to separate the cigarette packets from the suction cups, so that the cigarette packets are placed on the synchronous toothed belt for transportation. The prior art has the following defects: the suction cups always maintain the adsorption state. On the one hand, it is easy to cause dust or other impurities to be sucked into the suction cups after the suction cups are separated from the cigarette packets, resulting in blockage of the suction cups and their connected pipes, affecting the normal suction of the suction cups; on the other hand, it is easy to cause the transmission mechanism of the extractor to overcome the suction force of the suction cups to separate the cigarette packets from the suction cups by the baffles, increasing the operating load of the transmission mechanism of the extractor and affecting the service life of the transmission mechanism of the extractor.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0028] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figures 1 to 6 As shown, the cigarette pack conveying equipment of the embodiment of the utility model includes a first conveyor line 1, a second conveyor line 2 and a transfer mechanism 3, the first conveyor line 1 is used to transfer the cigarette pack 100 to the transfer end 11 along a first direction (the first direction is the X direction shown in the figure); the second conveyor line 2 is arranged on one side of the transfer end 11, and the second conveyor line 2 is used to transfer the cigarette pack 100 along a second direction (the second direction is the Y direction shown in the figure), and the first direction and the second direction are arranged at an angle; the transfer mechanism 3 includes a first driving member 31, a suction nozzle 32, a negative pressure machine and a control device 33, the first driving member 31 is transmission-connected with the suction nozzle 32, so that the suction nozzle 32 transfers the cigarette pack 100 of the transfer end 11 to the second conveyor line 2, the negative pressure machine is connected to the suction nozzle 32, and the control device 33 is used to control the start and stop of the suction nozzle 32.

[0032] It can be understood that, through the setting of the control device 33, after the first driving member 31 drives the suction nozzle 32 to transfer the cigarette pack 100 from the first conveyor line 1 to the second conveyor line 2, the control device 33 can control the suction nozzle 32 to stop sucking the cigarette pack 100, so that the cigarette pack 100 can be naturally placed on the second conveyor line 2 for transportation, and when the first driving member 31 drives the suction nozzle 32 to contact the next cigarette pack 100 on the first conveyor line 1, the control device 33 starts the suction nozzle 32 to suck the cigarette pack 100 with negative pressure, so as to reduce the suction nozzle 32 and the cigarette pack 100. 0 is still in the state of continuous adsorption during separation, so as to prevent dust or other impurities from entering the suction cup and causing blockage, and reduce the traditional structure of using the first driving member 31 to drive the suction nozzle 32 to stop the cigarette pack 100 at the stopping block so that the cigarette pack 100 and the suction nozzle 32 can be separated, so as to ensure the normal operation of the first driving member 31. When the suction nozzle 32 stops adsorbing the cigarette pack 100, it can be naturally placed on the second conveyor line 2, which is convenient and fast, and improves the convenience of the cigarette pack 100 from being transferred in the first direction by the first conveyor line 1 to being transferred in the second direction by the second conveyor line 2.

[0033] In this embodiment, if Figure 1 and Figure 2As shown in the figure, in order to reduce the continuous wear between the cigarette packet 100 and the conveying line, the first conveying line 1 adopts a combination of a motor and a conveyor belt. Through the intermittent operation of the conveyor belt driven by the motor, the cigarette packets 100 on the conveyor belt can be conveyed to the transfer end 11 one by one. The second conveying line 2 adopts a support block 21 and a conveyor chain 22 arranged above the support block 21. The support block 21 is arranged on one side of the conveyor belt, and the length of the support block 21 extends along the second direction. A plurality of scraping plates 23 are arranged at intervals on the conveyor chain 22. The conveyor chain 22 continuously drives to drive the scraping plates 23 to push the cigarette packets 100 on the support block 21 to move along the second direction. By controlling the device 33 to stop the suction of the suction nozzle 32 and separate the cigarette packet 100 from the suction nozzle 32, it is possible to avoid the situation where the scraping plate 23 pushes the cigarette packet 100 while the cigarette packet 100 is still adsorbed to the suction nozzle 32, resulting in wear of the cigarette packet 100 and the suction nozzle 32, improve the production quality of the cigarette packet 100, and reduce the wear of the suction nozzle 32.

[0034] Further, as Figure 3 , Figure 4 and Figure 5 shown, the control device 33 is communicated with the suction nozzle 32 through a connecting pipe 34. The control device 33 includes a fixed seat 331, a cover plate 332, a first turntable 333, a rotating shaft 334 and a second driving member 335. A receiving groove 3311 is recessed on the fixed seat 331. A first ventilation hole 3312 is penetrated through the bottom of the receiving groove 3311. The cover plate 332 seals the opening of the receiving groove 3311 to form a closed receiving cavity. A second ventilation hole 3321 is arranged at the position of the cover plate 332 corresponding to the first ventilation hole 3312. The first turntable 333 is rotatably arranged in the receiving cavity and sleeved on the outer periphery of the rotating shaft 334. A first communication port 3331 is arranged on the first turntable 333, and the length of the first communication port 3331 extends along the circumferential direction of the first turntable 333. A part of the rotating shaft 334 passes through the fixed seat 331 and extends outside the receiving cavity and is connected to the second driving member 335. The second driving member 335 drives the first turntable 333 to rotate through the rotating shaft 334, so that the first ventilation hole 3312 can be communicated with the second ventilation hole 3321 through the first communication port 3331, or the first ventilation hole 3312 is blocked by the first turntable 333 and cut off from the second ventilation hole 3321. The connecting pipe 34 includes a first ventilation pipe and a second ventilation pipe 341. The negative pressure machine is communicated with the first ventilation hole 3312 through the first ventilation pipe, and the second ventilation hole 3321 is communicated with the suction nozzle 32 through the second ventilation pipe 341.

[0035] It can be understood that by utilizing the second driving member 335 to drive the first rotating disk 333 to rotate, the first vent hole 3312 can be connected to the second vent hole 3321 through the first connecting port 3331, so that the negative pressure machine is connected to the suction nozzle 32, so that the suction nozzle 32 can absorb the cigarette pack 100; when the first rotating disk 333 rotates to the point where the first connecting port 3331 is misaligned with the first vent hole 3312 and the second vent hole 3321, the first vent hole 3312 is blocked by the first rotating disk 333 and is connected to the second vent hole 3321. 1 is separated, at this time, the negative pressure machine is blocked from the suction nozzle 32, and the cigarette pack 100 falls off the suction nozzle 32, that is, when the first driving member 31 drives the suction nozzle 32 to contact the cigarette pack 100 at the transfer end 11, the first ventilation hole 3312 can be connected with the second ventilation hole 3321 through the first connecting port 3331, until the first driving member 31 drives the suction nozzle 32 to transfer the cigarette pack 100 to the second conveyor line 2, and the second turntable 336 is driven by the second driving member 335 to separate the first ventilation hole 3312 from the second ventilation hole 3321.

[0036] It should be noted that the negative pressure machine is always kept running to avoid the situation where the negative pressure machine is repeatedly started and stopped and easily damaged, and negative pressure is always maintained in the first ventilation pipe, so that when the first connecting port 3331 connects the first ventilation hole 3312 with the second ventilation hole 3321, negative pressure can be generated in the second ventilation pipe 341, avoiding repeated starting and stopping and waiting for negative pressure to be formed in the connecting pipe 34 before the suction nozzle 32 has negative pressure, thereby reducing the reaction time of the suction nozzle 32 when it is started again.

[0037] Furthermore, the cover plate 332 is provided with an air leakage hole 3322, and the first rotating disk 333 is provided with an air leakage groove 3332 in a recessed manner on one side of the cover plate 332, and the air leakage groove 3332 is arranged at intervals on one side of the first connecting port 3331 along the rotation direction of the first rotating disk 333, and the second air vent 3321 can be connected with the air leakage hole 3322 through the air leakage groove 3332. By providing the air leakage groove 3332 on the first rotating disk 333 and connecting with the air leakage hole 3322 on the cover plate 332, when the first rotating disk 333 is rotated to the misalignment between the first connecting port 3331 and the second air vent 3321, the second air vent 3321 and the air leakage hole 3322 are connected through the air leakage groove 3332, so that the negative pressure in the second ventilation pipe 341 can be discharged in time, so that the cigarette pack 100 and the suction nozzle 32 can be separated in time.

[0038] Preferably, the air release groove 3332 includes a first pressure relief groove 33321, a connecting groove 33322, and a second pressure relief groove 33323. The first pressure relief groove 33321 and the second pressure relief groove 33323 are arranged at intervals along the radial direction of the first turntable 333, and the lengths of both the first pressure relief groove 33321 and the second pressure relief groove 33323 extend along the axis direction of the first turntable 333. The first pressure relief groove 33321 is communicated with the second pressure relief groove 33323 through the connecting groove 33322. The first pressure relief groove 33321 is communicated with the second ventilation hole 3321, and the second pressure relief groove 33323 is communicated with the air release hole 3322. Since the second turntable 336 is continuously driven by the second driving member 335 to rotate continuously, and the second ventilation pipe 341 has a certain length, in order to timely empty the negative pressure in the second ventilation pipe 341, the first pressure relief groove 33321 with a certain length is used in cooperation with the second pressure relief groove 33323 to continuously empty the second ventilation hole 3321 and the second ventilation pipe 341 connected thereto.

[0039] In some embodiments, the control device 33 further includes a second turntable 336. A second communication port 3361 is provided at a position corresponding to the first communication port 3331 on the second turntable 336. The second turntable 336 is arranged on the outer periphery of the rotating shaft 334 and fits with the first turntable 333. The first communication port 3331 is communicated with the second communication port 3361. It can be understood that both the first turntable 333 and the second turntable 336 are fixed to the outer periphery of the rotating shaft 334 by button head screws. By adjusting the installation angle of the second turntable 336, the overlapping area size between the first communication port 3331 and the second communication port 3361 is adjusted. That is, when the first communication port 3331 and the second communication port 3361 completely overlap, the communication area between the first ventilation hole 3312 and the second ventilation hole 3321 is the largest, and the communication time between the first ventilation hole 3312 and the second ventilation hole 3321 is the longest. By adjusting the misalignment distance between the first communication port 3331 and the second communication port 3361 to adjust the communication duration between the first ventilation hole 3312 and the second ventilation hole 3321, it is ensured that the suction nozzle 32 can timely adsorb the cigarette pack 100 and timely separate from the cigarette pack 100.

[0040] Exemplarily, the first ventilation hole 3312 and the second ventilation hole 3321 are arranged opposite to each other. If the first communication port 3331 and the second communication port 3361 are misaligned, taking the case where the second communication port 3361 first contacts the first ventilation hole 3312 during the rotation of the rotation shaft 334 as an example, when the second communication port 3361 is in communication with the first ventilation hole 3312, the first communication port 3331 has not yet rotated to a position where it can be in communication with the second ventilation hole 3321. At this time, the first ventilation hole 3312 and the second ventilation hole 3321 are still spaced apart. If the first communication port 3331 and the second communication port 3361 coincide, then when the second communication port 3361 is in communication with the first ventilation hole 3312, the first communication port 3331 is synchronously in communication with the second ventilation hole 3321. Therefore, by adjusting the installation angle of the second turntable 336, the installation angle of the second turntable 336 can be adjusted to adjust the misalignment size between the first communication port 3331 and the second communication port 3361, and the on-off duration of the first ventilation hole 3312 and the second ventilation hole 3321 can be adjusted.

[0041] Furthermore, at least two second ventilation holes 3321 are provided on the cover plate 332, and the connecting line of the centers of all the second ventilation holes 3321 passes through the center of the cover plate 332. The first ventilation hole 3312 can be in communication with all the second ventilation holes 3321 through the first communication port 3331. Each second ventilation hole 3321 corresponds to a second ventilation pipe 341 connected to a suction nozzle 32 of a transfer mechanism 3. By providing a plurality of second ventilation holes 3321 on the cover plate 332, and each second ventilation hole 3321 corresponds to a suction nozzle 32 of a transfer mechanism 3, the control of the suction nozzles 32 of a plurality of transfer mechanisms 3 can be realized, and the practicability of the control device 33 can be improved.

[0042] Specifically, the cigarette pack conveying device includes two first conveying lines 1 arranged at intervals in the vertical direction (the vertical direction is the Z direction shown in the figure, and in this embodiment, the X direction, the Y direction, and the Z direction are perpendicular to each other), two second conveying lines 2, and two transfer mechanisms 3. The cigarette packs 100 on the upper first conveying line 1 are transferred to the upper second conveying line 2 through the upper transfer mechanism 3, and the cigarette packs 100 on the lower first conveying line 1 are transferred to the lower second conveying line 2 through the lower transfer mechanism 3. Two second ventilation holes 3321 are provided on the cover plate 332, and the suction nozzle 32 of each transfer mechanism 3 is respectively in communication with a second ventilation hole 3321. By providing two second ventilation holes 3321 to realize the control of two transfer mechanisms 3, the practicability of the control device 33 is improved, the number of negative pressure machines invested is reduced, and one negative pressure machine can realize the negative pressure control of two transfer mechanisms 3, reducing the investment in production costs.

[0043] Optionally, the connection lines of the centers of all the second ventilation holes 3321 are located on the same radius of the cover plate 332. Then, by rotating the turntable, the first ventilation hole 3312 can be synchronously communicated with or disconnected from all the second ventilation holes 3321.

[0044] However, in this embodiment, the two second ventilation holes 3321 are symmetrically distributed about the center of the cover plate 332, that is, the two second ventilation holes 3321 are respectively the first control hole 33211 and the second control hole 33212, and the first control hole 33211 and the second control hole 33212 are symmetrically distributed about the rotation axis of the rotating shaft 334. Two first ventilation holes 3312 are respectively arranged on the fixed seat 331 corresponding to the two second ventilation holes 3321. The two first ventilation holes 3312 are respectively the third control hole 33121 and the fourth control hole 33122. During the rotation of the first turntable 333, the first control hole 33211 is communicated with the third control hole 33121 through the first communication port 3331; or the second control hole 33212 is communicated with the fourth control hole 33122 through the first communication port 3331. The first control hole 33211 is communicated with the suction nozzle 32 of the transfer mechanism 3 above, and the second control hole 33212 is communicated with the suction nozzle 32 of the transfer mechanism 3 below. The two first driving members 31 are alternately driven. In this embodiment, the support blocks 21 of the two transfer mechanisms 3 converge to the same conveyor line along the conveying direction of the second conveyor line 2. Therefore, the alternate driving of the two first driving members 31 can ensure the production rhythm of the upper and lower first conveyor lines 1, the second conveyor line 2 and the transfer mechanism 3, and at the same time, it is also convenient to improve the coordination of the cigarette packs 100 on the subsequent two support blocks 21 converging to the same conveyor line.

[0045] It should be noted that the first communication port 3331 is an arc-shaped port, and the length of the arc-shaped port extends along the circumferential direction of the first turntable 333, but the central angle of the arc-shaped port cannot exceed 180°, so as to ensure that the first communication port 3331 can only be communicated with one of the first control hole 33211 and the second control hole 33212, thereby improving the adaptability of the control device 33 and the first driving members 31 of the two transfer mechanisms 3 for alternate driving.

[0046] Exemplarily, the two first driving members 31 are respectively the first transmission member and the second transmission member. The first driving member 31 of the transfer mechanism 3 above is the first transmission member. When the first transmission member pushes the suction nozzle 32 to contact the cigarette pack 100 at the transfer end 11 of the first conveyor line 1 above, until the first transmission member drives the suction nozzle 32 to move the cigarette pack 100 to the second conveyor line 2 above, the first communication port 3331 is communicated with the first control hole 33211, and the first communication port 3331 is blocked from the second control hole 33212. At this time, the second driving member 335 drives the suction nozzle 32 to move towards the cigarette pack 100 at the transfer end 11 of the first conveyor line 1 below. When the second driving member 335 drives the suction nozzle 32 to contact the cigarette pack 100 at the transfer end 11 of the first conveyor line 1 below, the first communication port 3331 rotates to be communicated with the second control hole 33212, until the second transmission member drives the suction nozzle 32 to move the cigarette pack 100 to the second conveyor line 2 below. At this time, the first communication port 3331 is blocked from the first control hole 33211. By repeating this process, the on-off of the two second ventilation holes 3321 and the alternating cooperation of the first driving members 31 of the two transfer mechanisms 3 are realized.

[0047] In some other embodiments, the control device 33 further includes a first sealing member 337, and the first sealing member 337 is disposed between the cover plate 332 and the fixed seat 331. By providing the first sealing member 337, the sealing performance between the cover plate 332 and the fixed seat 331 can be enhanced, and the situation of air leakage in the accommodation cavity and resulting pressure relief can be avoided.

[0048] Optionally, the control device 33 further includes a second sealing member 338, and the second sealing member 338 is sleeved on the outer periphery of the first turntable 333. By providing the second sealing member 338, the sealing performance between the first turntable 333 and the cavity wall of the accommodation cavity can be enhanced, and the blocking performance of the first ventilation hole 3312 and the second ventilation hole 3321 when the first turntable 333 rotates to make the first communication port 3331 misaligned with the ventilation hole can be improved. Of course, in this embodiment, when the second turntable 336 is provided to cooperate with the first turntable 333, the second sealing member 338 can be sleeved on the outer periphery of the second turntable 336, or the second sealing member 338 can be sleeved on the outer peripheries of both the first turntable 333 and the second turntable 336.

[0049] Preferably, a plug-in portion 3323 is protrudingly provided on one side of the cover plate 332 facing the fixed seat 331. The plug-in portion 3323 is inserted into the receiving groove 3311 and fits against the groove wall of the receiving groove 3311. Through the arrangement of the plug-in portion 3323, on the one hand, the guiding property of the connection between the cover plate 332 and the fixed seat 331 can be improved, and the plug-in portion 3323 cooperates with the groove wall of the receiving groove 3311 to effectively improve the installation accuracy of the cover plate 332 and the connection stability between the cover plate 332 and the fixed seat 331; on the other hand, the contact surface of the connection between the cover plate 332 and the fixed seat 331 can also be increased, further improving the sealing performance between the cover plate 332 and the fixed seat 331.

[0050] Furthermore, as Figure 6 shown, the transfer mechanism 3 further includes a mounting plate 35 and a spring 36. The driving end of the first driving member 31 is provided with a mounting plate 35. The suction nozzle 32 is disposed on the mounting plate 35. A plurality of springs 36 are spaced apart on one side of the mounting plate 35 facing the suction nozzle 32. The spring 36 always has a tendency to push the cigarette pack 100 away from the suction nozzle 32. It can be understood that the end of the spring 36 away from the mounting plate 35 should protrude slightly from the working surface of the suction nozzle 32. That is, the first driving member 31 drives the mounting plate 35 to approach the cigarette pack 100 at the transfer end 11. The cigarette pack 100 first contacts the spring 36 and overcomes the elastic force of the spring 36 to be adsorbed onto the suction nozzle 32. The first driving member 31 drives the mounting plate 35 to retract to drive the suction nozzle 32 to transfer the cigarette pack 100 to the second conveying line 2. At this time, the control device 33 controls the suction nozzle 32 to stop adsorbing, and the cigarette pack 100 is separated from the suction nozzle 32 under the elastic action of the spring 36, avoiding the situation that it is difficult to separate the cigarette pack 100 from the suction nozzle 32 due to some residual pressure in the suction nozzle 32.

[0051] In other embodiments, the first driving member 31 and the second driving member 335 can be driven by the same motor, and cooperate with gears to drive the connecting rod to realize the linear movement of the suction nozzle 32, and cooperate with gears or a conveyor belt to realize the rotation of the rotating shaft 334, which can reduce the investment in driving members, save the overall occupied space of the equipment and the production cost. Of course, the first driving member 31 can also directly adopt a linear driving mechanism such as a cylinder or an electric cylinder, and the second driving member 335 can be directly driven by a motor.

For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
